3.14 Placarding
All inoperative items must be placarded to inform crew members of equipment condition.
While the MEL for some items may require specific wording, the majority of items leave the placard wording and location to be determined by the operator.
The operator shall provide the capability and instructions to the flight crew to ensure that the placard is in place prior to the aircraft being dispatched.
Note: The exclusion of an asterisk in a MMEL does not preclude the requirement for placarding.
3.14.1 Requirements to PlacardPlacard Control Placarding will be carried out in accordance with the placarding procedures established
and set out in the operators approved MCM. The method of placarding control must ensure that all inoperative items are placarded and placards are removed and accounted
for when the defect is cleared.
3.14.2 Procedures The equipmentsystem shall be placarded so as to inform the crew members of the
inoperative conditions of the item. To the extent practicable, placards must be located as indicated in the MEL, or adjacent to the control or indicator affected.
3.14.3 Placard Criteria Placards should be self adhesive. The placard may be in two parts. Part One should list a
description of the defect and the defect control number and should be attached to the log book for crew reference. Part Two should list the system affected and the defect control
number and be fixed in the appropriate location. A MEL control sheet attached to the log book could serve the same purpose as Part One above.
3.14.4 Multiple Placards If more than one placard is required for a MEL item, provision must be made to ensure
that all placards are removed when the defect is cleared. 3.14.5 Temporary Placards
If a defect occurs at a base where maintenance personnel are not available, the flight or cabin crew may install a temporary placard as required by the MEL. The aircraft may
continue on a planned itinerary to a base where maintenance will rectify or re-defer in accordance with the approved deferral system.
3.15 Dispatch
Dispatch for the purpose of the MELMMEL refers to the moment the airplane starts its takeoff roll. In the case of a helicopter, it refers to the moment the helicopter
commences air or ground taxi. The MEL is approved on the basis that equipment will be operative for takeoff unless the appropriate MEL procedures have been carried out. The
operators MEL shall include procedures to deal with any failures which occur between the start of taxi or push back and takeoff brake release. Any failure which occurs after
takeoff commences shall be dealt with as an in-flight failure, by reference to the appropriate section of the aircraft flight manual, if necessary. After takeoff commences,
no MEL action is required, until the completion of the next landing.
3.15.1 Operational and Maintenance Items a
Any item of equipment in the MEL, which when inoperative would require an operating or maintenance procedure to ensure the required level of safety, shall be
so identified in the remarks or exceptions column of the MEL. This will normally be O for an operating procedure, or M for a maintenance procedure.
OM means both operating and maintenance procedures are required.
b O Items
1.
Aircraft with inoperative equipment requiring an operating procedure may be returned to service following completion of the required MEL procedure for
deferral.
2.
Operating procedures are normally carried out by qualified flight or cabin crew, but may be accomplished by other qualified, approved personnel.
c M Items
1. Aircraft with inoperative equipment requiring a maintenance procedure
may be returned to service following completion of the required MEL procedure for deferral.
2. Maintenance procedures are normally accomplished by maintenance
personnel, but some elementary maintenance tasks may be carried out by crew members or other qualified, approved personnel See Section
3.15.2.
3.
Air crews may not perform maintenance procedures if the defect involves an item designated in the MEL with a M - Maintenance Personnel
Required . In this circumstance, the aircraft may not proceed until
authorized maintenance personnel carry out the specified procedure Not all MMELs use the annotation M.
3.15.2 Elementary Work Some elementary work called for in the MEL may be accomplished by crew members,
or others, who have been trained and approved to do so according to the regulations and standards in Maintenance Standard.
